Medication Basics
Generic Name: Torsemide
Brand Name: Demadex
Medication Class: Diuretic – Loop
Description
Loop diuretics are widely used to treat several cardiac conditions which can cause fluid to back up all over the body; most notably, chronic or congestive heart failure. The loop diuretics are probably the single most effective drug to increase fluid elimination through urination and work by increasing the amount of sodium the kidney eliminates. They can often be used with other types of diuretics if they are ineffective by themselves. They can also be used to treat high blood pressure that fails to respond to multiple medications. Torsemide and bumetanide are better absorbed from the gut than furosemide, particularly when a lot of fluid has accumulated in the body.
